Given circle P centred at the origin, with a radius of 4 units. Circle P is not a function
domain : -4 ≤ x ≤ 4
f(0) = 0

Circle P is a function.
x2 + y2 = 16

Which of the following could be the graph of the equation y = -2x + 5

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle
